Agroecological engineering

2015

Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…

A Macroeconomic Estimation of the Education Production Function

2007

07/002; The aim of this paper is to test the existence of an education production function based on data resulting from international surveys of pupil assets. The results of the estimates, using first the total sample, and then making distinctions according to the economic level of the country, show significant differences concerning the relationships between educational inputs and outputs. Thus, inconsistencies found in former analyses in terms of estimating the education production function can partially be explained by the fact that they failed to take into account the economic level of the countries analysed.

Economic crisis and educational crisis : looking ahead

1986

The worldwide economic crisis has now been with us for a good ten years and, for many countries, the end of the tunnel is not yet in sight and is probably a long way off. So what kind of crisis is this, that can continue for so long, given the fact that, etymologically, the term denotes a brief, crucial moment when the outcome of a troubled situation is decided, for better or for worse? Infelicitous as the term commonly used to describe the present state of the world economy may be, it is none the less true that what is designated as a crisis encompasses a historical phase in which economic growth is lower than in the preceding phase and the problems bound up with certain economic trends (i…

Autonomous management of Quality of Service and security in an Internet of Things environment

2019

Nowadays, the Internet of Things (IoT) is becoming important in our daily lives thanks to technological advances. This paradigm aims to improve the quality of human life through automating several tasks. In this context, service level guarantee within IoT environments is a major challenge while considering a massive deployment of IoT applications and services as well as extending their usage to different domains. The IoT service level can be characterized in two parts: Quality of Service (QoS) and security. Moreover, this service level must be managed in an autonomic manner within the IoT environment given the heterogeneity and the size of its infrastructure making it difficult, even imposs…

A number of phonetic and phonological changes have lately been observed in most geographical varieties of British English. This phenomenon seems to have been accelerated by increasing social and geographical mobility in the past decades. Based on a corpus mainly consisting of several hours of spontaneous interaction between a number of native NW Yorkshire speakers divided into different age groups, this research identifies and analyses several segmental and suprasegmental innovations observed in apparent time in a set of accents associated with a circumscribed geographical area. This thesis discusses the motivation behind some of these changes and addresses the question of whether the same …

Formulation, process conditions, and biological evaluation of dairy mixed gels containing fava bean and milk proteins: Effect on protein retention in…

2019

International audience; Food formulation and process conditions can indirectly influence AA digestibility and bioavailability. Here we investigated the effects of formulation and process conditions used in the manufacture of novel blended dairy gels (called "mixed gels" here) containing fava bean (Vicia faba) globular proteins on both protein composition and metabolism when given to young rats. Three mixed dairy gels containing casein micelles and fava bean proteins were produced either by chemical acidification (A) with glucono-δ-lactone (GDL) or by lactic acid fermentation. Fermented gels containing casein and fava bean proteins were produced without (F) or with (FW) whey proteins. The AA…

Geometric quality and appearance of surfaces : local and global approaches

2012

Accounting for customers' perception of manufactured goods has become a major challenge for the industry. This process is to be established from early design to retail. Customers are nowadays more aware and detail oriented about perceived quality of products. This allows one to set not only an estimated price but also the expected quality of the product. Surface appearance analysis has therefore become a key industrial issue. Two approaches are proposed here to formalize the detection methodology and provide objective criteria for experts to evaluate surface anomalies. The first proposed approach is based on surface metrology. It consists in analyzing the measured topologies in order to bin…
